IMPROVEMENT IN PERCHES FOR DUMPlNG-CARS.

Specification forming part of Letters Patent No. 147,863, dated February24, 1874; application filed September 13, 1873.

.which the draw-heads may be arranged at standard height, being stiffand strong enough to support the rocker-bed from its ends, and

avoiding the continual annoyance from rotting of the parts andconsequent wrecking of the cars.

My invention consists in making the perch oi the dumpingcar of two barsof channeliron, T- beam, or .other form of iron, and fastening itlaterally, in such a manner that the draw-rigging passes between them,and the whole structure becomes stiffer and stronger.

Hitherto the perches of dumping-cars were made of timber, which are notonly clumsy in appearance, but lack strength and break often down,causingthereby serious and expensive accidents. The draw-heads, beingnecessarily. placed above or below the timber, cause the shocks orstrains to be taken out of the center line.

By constructingthe porch in the manner proposed, the center of draft canbe established at any height, and the perch forms thereby a stiffbackbone for the frame of the car. The drawheads, rocker-bed, drawrigging, and other parts can be better and stronger arranged, and thedumping-car be made thereby more serviceable and safer for use.

In the drawing, A A are longitudinal bars, of channel-iron, T-beam, orother girder iron, which connect the trucks of the car, and form thebackbone of the car. The bars A are laterally connected at both ends byL-irons or other bars, and carry between them the drawsprings anddraw-heads, either at the center of their height or above or below thesame. The draw-heads may thereby be arranged at stan d ard'heighta pointof great importanceand transfer the shocks and strains near the centerof the perch, instead of above or below the same, thus avoiding thedanger of breaking and wrecking of the train while in use. These percheslast longer, require less repairs and admit the easier arrangement ofthe other part of the dumping-cars thereon.

Having thus described my invention, I claim as. new and desire to secureby Letters Patent The combination, with the truck-frame of adumping-car, of a perch composedof two connected channel iron bars thathave the drawrigging arranged between them, as and for the purposespecified.

GEORGE RICHARDS.
